Western corn rootworm is an important corn pest in the U.S. Some farmers noted unexpected corn rootworm injury of transgenic hybrids as early as 2008; however, the full extent of product performance is still not fully understood. We conducted telephone focus groups with farmers in 2013 to gain their perspective of current and future issues for corn rootworm. Respondents were surprised how quickly corn rootworm injury escalated in their fields and were disappointed with incorrect diagnoses from consultants and seed companies. Most participating farmers saw university Extension as an unbiased source of information.
